Board President Bill Thompson agreed that Crew’s support has crumbled.

“Even a one-year extension is in jeopardy,” said Thompson, who, along with two other members, wants Crew to remain.

Thompson cited a series of scandals and blunders, including reports on test-tampering and attendance-padding in city schools, and Crew’s flip comment last week that Councilman Stephen Fiala (R-Staten Island) was “too short” to call for Crew’s removal.

Crew, who had still seemed a shoo-in for a one-year renewal, angered several board members this week by bringing in a lawyer to ask for a two- or three-year extension — and fatter pension benefits, sources said.

Crew issued only a terse statement yesterday: “I have expressed my desire to remain as chancellor to the president of the board. I also discussed with him the conditions under which I felt I could be most effective. I now await the board’s response.”

As Crew’s prospects dwindled, Staten Island Borough President Guy Molinari called on the board to let him go — and look for a new chancellor “who can pick up the pieces and breathe more enthusiasm and life into the system.”

Molinari’s appointee to the board, Jerry Cammarata, called today’s meeting along with Mayor Giuliani’s two appointees, Irene Impellizzeri and Deputy Mayor Ninfa Segarra.

One board source said Giuliani was behind the bid to get rid of Crew. Earlier this year, Giuliani orchestrated a 4-3 vote to reject Crew’s school-construction budget and push through his own.

Giuliani declined for a second day in a row to give Crew a vote of confidence, saying only: “I think the board has serious concerns that stem from a number of things that have happened over the last several months, including some things that happened last week.

“The board is going to have to make a determination about that. I’ll consult them and talk to them about that.”

Thomson said she has major reservations about voting to renew Crew’s $245,000-a-year contract, which expires in June. He has served four years — breaking records for survival. He would become vested in his pension in October.

Thomson said she was “terribly disappointed” that Crew had failed to outline his agenda — or express any passion to pursue it.

“We have not had a single conversation about strategy, goals, vision — the things that I want to hear from the chancellor,” she said. “All I have heard, through the press, is that he has sent his lawyer to discuss the terms and finances of his contract.”
